Good value compared to most, and an odor is expected if it is really NAC, which contains sulfur
My wife and I have been taking this brand NAC for a few months. I have no way to know how good it is, as supplements are not well regulated, so I can't comment on that. We take NAC because if may have value if we become infected with the novel coronavirus, that causes COVID-19. And with regard to the odor, this is my experience: I noticed the normally expected sulfur odor when I opened the bottle to distribute the pills to my daily Rx sorter, but I have never noticed any odor when I am taking the pills each day. Yes, it is mildly annoying for a few minutes upon opening the bottle for the first time, but it has not bothered me since, and when I just opened it again, today, I had to hold the open bottle near my nose to notice any odor at all. As others have noted, if it is actually NAC, it is supposed to smell of sulfur ("rotten eggs"). That just indicates it is likely to be real NAC.

It works.
This stuff is great. Of course speak with your nurse, doctor, specialist or pharmacist but for me it works wonders. I have lupus SLE. That condition caused me to have a very rare condition called Shrinking lung disease. I also developed lupus nephritis and fibromyalgia. So my body is waving the white flag of surrender. I began taking this and have seen a decrease in pain and inflammation. Because lupus is a real crap head, I often get pericarditis and pleurisy as well. NAC has been a life saver in that area. I highly recommend this product and I love this brand.

Waste of time and money. Strong Bad smell like old fish
Waste of time and money. Strong Bad smell like old fish. I tried one of these and the fishy smell lingered with me 24 hours. Not worth it. I have used other brands of NAC, and one had NO smell at all, and the other just barely noticeable. I feel like something is wrong here. Lots of positive reviews, but 20% negative, which I missed. The bottle I got was bad, Maybe a bad batch, or maybe got overheated in manufacturing, storage or shipping, which is a Quality Control Issue and not my problem. I am throwing out and will not buy again. Nor will I buy this brand again due to quality control issues. Bad product. Waste of money.

3rd party lab tested
It's a nice big bottle and should last a while. This bottle says take 1-2 capsules daily, the kind I had previously, at the same dosage, only said to take one.

Crappy quality control
Unusable chaos. Nearly all the pills stuck together, and welded into a glue-like mass, or disintegrated into foggy, spidery weblike filaments exploding wall-to-wall within the bottle. At first, on removing the clear plastic seal and unscrewing the bottle’s lid, I thought the spiderweb-like filaments I was running into were from the cotton padding one initially finds in bottles of pills to keep the pills more or less immobile. Not true. Instead, inside the bottle was, on one side, the mass of capsules all stuck together in a congealed mass and firmly attached to one wall of the plastic bottle. And across the rest of the bottle’s interior were spidery wall-to-wall webs of threadlike filaments — the residue of some sort of disintegrative process originating in the breakdown of the capsules’ walls or contents or both. The capsules themselves are unreclaimable, given their congealed-to-each other condition. A little pressure on one or several could not free them from the larger, firmly glued-together, mass. Instead, the capsule wall immediately ruptures, spilling the chemical powders inside the capsules onto my fingertips and elsewhere. So, what Best Naturals sent me — in response to my advance payment — was not any proper N-Acetyl Cysteine supplement, but an unholy mess. I first intended to simply contact the company and ask for a proper bottle of the NAC supplement or, possibly, a refund of the entire amount of my expenditure. However, the number of hoops the Best Naturals website requires one to jump through to get decent service convinced me this company needs to learn a lesson. Thus this posting.
